Email sent from Comodo SSL certificate with the same title as follows: ” Your PositiveSSL Certificate for seosieutoc.com “, in the mail with attachment 1 zip seosieutoc_com.zip consists of two files:

seosieutoc_com.crt
seosieutoc_com.ca-bundle
You use any editor, Notepad ++ for example, open the file seosieutoc_com.crt copy and paste the entire contents of the file on top of seosieutoc_com.ca-bundle saved in the file ssl-bundle.crt

At this time, the certificate file ssl-bundle.crt will contain the contents of two files .crt and .ca-bundle

2. Install SSL certificates

This step alone operation on server installation HocVPS Script the server installed Nginx server manually or else how do you keep reading same carefully to understand. Entanglements place to leave a comment I will support always.

Create a file folder containing the certificate:

mkdir -p / etc / nginx / ssl / seosieutoc_com /
Save the content certificate file in this folder, copy / paste using Nano editor

nano /etc/nginx/ssl/seosieutoc_com/ssl-bundle.crt
Save the content shared folder Private Key:

nano /etc/nginx/ssl/seosieutoc_com/seosieutoc_com.key
Creating parameters DH 2048 bit file, the process will generate a while:

mkdir / etc / nginx / cert /
openssl-out /etc/nginx/cert/dhparam.pem[19459015dhparam2048]
Next, we will adjust the Nginx configuration file. For example, your domain name is seosieutoc.com the file will be the path configuration is /etc/nginx/conf.d/seosieutoc.com.conf

Open up the configuration file with nano

nano /etc/nginx/conf.d/seosieutoc.com.conf

Configuring SSL with port management HocVPS Admin Script

If you install SSL for the domain name used HocVPS Script, add SSL configuration required when using the port. For example, if your installation to the default port 2313 .

Find block server … line listen 2313;

Add text and paragraph ssl SSL configuration similar to below:

server {
listen 2313 ssl http2 ;
access_log off;
log_not_found off;
error_log off;
/home/seosieutoc.com/private_html root;
index.htm index.html index.php index;
server_name seosieutoc.com;

# SSL
ssl_certificate /etc/nginx/ssl/seosieutoc_com/ssl-bundle.crt;
ssl_certificate_key /etc/nginx/ssl/seosieutoc_com/seosieutoc_com.key;
TLSv1 TLSv1.1 ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers’ ECDHE-ECDSA-CHACHA20-POLY1305: ECDHE-RSA-CHACHA20-POLY1305: ECDHE AES128-GCM-ECDSA-SHA256-: RSA-AES128-ECDHE-GCM-SHA256: ECDHE AES256-GCM-ECDSA-SHA384-: ECDHE- RSA-AES256-GCM-SHA384: DHE-RSA-AES128-GCM-SHA256: DHE-RSA-AES256-GCM-SHA384: ECDHE-ECDSA-AES128-SHA256: RSA-AES128-ECDHE-SHA256: ECDHE-ECDSA-AES128- SHA: RSA-AES256-ECDHE-SHA384: RSA-AES128-ECDHE-SHA: ECDHE-ECDSA-AES256-SHA384: ECDHE AES256-SHA-ECDSA-: RSA-AES256-ECDHE-SHA: DHE-RSA-AES128-SHA256: DHE-RSA-AES128-SHA: DHE-RSA-AES256-SHA256: DHE-RSA-AES256-SHA: ECDHE-ECDSA-DES-CBC3-SHA: ECDHE-RSA-DES-CBC3-SHA: EDH-RSA-DES CBC3-SHA: AES128-GCM-SHA256: AES256-GCM-SHA384: AES128-SHA256: AES256-SHA256: AES128-SHA: AES256-SHA: DES-CBC3-SHA:!

auth_basic “Restricted”;
auth_basic_user_file /home/seosieutoc.com/private_html/hocvps/.htpasswd;


Now HocVPS Script link Admin login will be https://seosieutoc.com

Nginx configuration file will eventually be similar to the following:
